Various methods of payment have been developed to cope with different situations in international trade. When the political and economic situation in the importing country makes payment uncertain or when the buyer’s credit standing is dubious, the exporter may prefer cash in advance or partial cash in advance. In this case, the importer has no guarantee that the exporter will fulfill his obligations once he has made payment by cash.
【正确答案】：在国际贸易中巳经发展出各种付款方式以解决不同形势下付款的问题。当进口国的政治和经济形势使付款不稳定或者当买方的信誉让人感到怀疑的时候，出口商喜欢采用预付现金或部分预付现金。在这种情况下，进口商在预付现金后不能保障出口商履行其责任。
